Operation Scan Pyramids began on 25 October to search for new chambers inside four pyramids including Khufu’s, the tallest, also known as the Great Pyramid of Giza.

Two weeks on the team of architects and scientists from Egypt, France, Canada and Japan said in a joint statement they had observed “thermal anomalies” on the monuments, including on the Khufu pyramid.

“The teams have concluded the existence of several thermal anomalies that were observed on all monuments during the heating up or the cooling down phases,” the statement said.

“To explain such anomalies a lot of hypothesis and possibilities could be drawn up: presence of voids behind the surface, internal air currents.”

In particular, it said, an “impressive” anomaly was found “on the eastern side of the Khufu pyramid at ground level”.

Thermal scanning of the massive structure indicated that some of the limestone blocks were hotter than others.

“This area should be the subject of further investigation during the subsequent phases of the project,” which was expected to last until the end of 2016, the statement added.

“Khufu will offer us today one of its secrets,” the Egyptian antiquities minister, Mamduh al-Damati, told reporters at the pyramid.

Neither he nor the experts provided any tangible explanation for the anomalies, which could indicate the existence of a secret chamber.

The project also involves thermal scanning at the Khafre pyramid of Giza as well as two pyramids in Dahshur, all of them south of Cairo.

As the project will continue until the end of 2016, researchers expect more discoveries to unfold.

Khufu’s pyramid, also known as the Great Pyramid of Giza or the Pyramid of Cheops, was built by the by the son of Snefru, founder of the fourth dynasty (2,575-2,465 BC), and is the oldest and tallest of the three pyramids in Giza. It is also the oldest of the Seven Wonders of the Ancient World, and the only one that has remained largely intact. Khafre was built by the son of Khufu

I think someone should start checking the stones on Khufu’s top layer. Some might be missing or back.
If you take 149 / 152 and 300 ( That is the lenghts from Menka to Khafre to Khufu back to Menka ratioed to Pi 3.143…… ) you get a minus 31, a plus 30 and a minus 28. Total Minus 29. The exact heading degrees from Menka to Khafre. My blog link on my FB.
